Introduction: Aquarium Robo Brush
Scrub algae and dirt from aquarium rocks with this small footprint, but highly efficient device using the rotary head from a battery-powered toothbrush.
Step 1: Things You Will Need
- Brush head from a battery-powered toothbrush. I used one for an Oral Action toothbrush. It has a drillable extension on the top that allows for a deeper hole for attachment pin. Other brands may work as well.
- 3/8 in wood dowel (or larger) -but make sure it will fit in your drill chuck.
- 1/8 in wood dowel
- Small saw
- Super Glue
Step 2: Separate Rotary Brush From Brush Head
Step 3: Drill 3/16 In. Deep Blind Hole in Top of Brush With a 1/8 In. Drill Bit
Step 4: Drill Hole in End of 3/8 In. Dowel
Use the same 1/8 in drill bit used for the brush hole to drill a 3/8 in. deep hole in the dowel cut to appropriate length for your aquarium. Don't make dowel any longer than necessary.
Step 5: Super Glue Short Piece of 1/8 Dowel Into Brush Hole
Step 6: Super Glue Brush to End OF Dowel With Hole
Step 7: Demo Video of Brush in Action
